A carbon footprint is defined as the total amount of greenhouse gases emitted into the atmosphere, such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), expressed in equivalent tons of CO2. It is associated with the activities of an individual, a community, an organisation, a process, a product or service, or an event, among other things. Individual carbon footprint can thus be termed as the total amount of greenhouse gases produced by our personal actions such as transportation, household activities, clothing and food. A product’s carbon footprint measures the total amount of greenhouse gas emissions from its life cycle – from raw material extraction and production to the final use by consumers including recycling or disposal. A company’s carbon footprint determines the greenhouse gas emissions from across its operations, including power generation used in building structures, industrial activities, and machinery and equipment. The carbon footprint of a country considers the greenhouse gas emissions from total energy and material utilisation, plants and other carbon sequestrations, as well as indirect and direct emissions from import and export processes.
